'What Was There' project adds a pinch of history to augmented reality

So, it works as such. You dig up ancient photos -- a few generations prior, or even a few decades ago -- scan 'em in, and tag them to their rightful place on Google Maps. Then, folks who visit the 'What Was Here' project website or download the iOS app (all linked below) will be able to see what kind of world they'd be living in if Uncle Rico's time machine actually worked. 'Course, the initiative needs you, you and you to participate if it's to be dubbed a success, so we'd recommend using whatever's left of your weekend to contribute. And then send your mum a "thinking of you" letter using the very map you're improving. Who said retro had to be retro, anyway?
